Abstract

A method and apparatus are provided for passing a client from a first server to which the client was connected for accessing a resource, to a second server for accessing the resource. While executing, the first server ceases to respond to the client. After the client detects that the first server has ceased to respond to the client, the client is automatically connected with the second server that has access to the resource. After automatically connecting the client, the client accesses the resource through the second server. The client stores information about the state of the session with the first server so that processing can continue where it left off after the client connects with the second server. The client may be pre-connected to the second server prior to the failure of the first server to reduce the latency caused by switching in response to a failure. The second server may be configured to pre-parse the commands that the client issues to the first server to further reduce the latency associated with switching to the second server.
